COCK` O'R FAUCE'l.

Application led May 12, 1922. Serial No. 560,318.

tain new and useful Improvements in a Cock or Faucet; and I do hereby declare the fol-y lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates` to a valve, faucet or cock principally adapted for use in connection with lavatories and bathtubs.

The principal object is to provide a valve of this nature which will be self-closing, as

through Apressure of water, expansion o`f a spring, or both, after actuation and release.

It is aimed to generally improve and render a device of this type more eiiicient and vto produce one which is self-closing, hasv a compression action, may have a single vhandle to control a plurality of valves, one having fa single body or casing through r which either hot or cold water may pass under control of said valves, and one having novel plugs attachable to the casing and adapted to mount the water control valves and as well serve as the connecting means between the casing and. the water supply ipes.

lVith the above and additional objects in view, the invention has been embodied in preferred forms as hereinafter described and illustrated in accompanying drawings.

In said drawings Figure 1 is a view of the improved sink faucet partly in front elevation and partly in longitudinal section;

Figure 2 is a plan view;

Figure 3 is a cross sectional View on the line 3 3 of Figure 1; and

Figure 4 is a cross sectional view on the line 41-4 of Figure 1.

Like reference characters designate like or similar parts in the different views.

Referring specically to the drawingsand first to the device of Figures 1 to L1, the embodiment is preferably adapted for use as a sink faucet but of course it is obvious that it may be applied to any other suitable use. The faucet is shown at A which may have a hollow casing 10 from which a discharge spout or neck 11 extends as usual, An operating stem 12 is turnably mounted in the casing 10, having its lower end journaled in a bearing 13 within the casing and in a suitable cap or closure 14 screw threaded to the casing as` at 15. Exteriorly of the body, a suitable handle 16 is rigidly secured to the steml 12. The handle may be of any suitable construction, but preferably has the words fHot and-Cold delineated thereon toV inform the user asy to the direction of turning for-hot and cold water, respectively.

Screw ,threaded into `the casing 10 asat 17 are pipesor plugs 18 having shoulders 19 to abut the casing. Slidably -mounted in boresor passagewaysv 19alongitudinally of the plugs 18. are valve stems or rods 20, preferably of less diameter thanthe passage-l The rods 2O` also slidably pass? ways 19. through suitable heads 21, in pipes or plugs 18 and disposed against the inner ends ofthe'plugs 18. 2O ,preferably have enlargements22 thereon and between the enlargements 22 and heads 21, expansive coil springs 23 are provided about the stems. Said springs 23 urgethe stems 20 toward the `operating stem 12.

Thel inner ends of vthe stems Extending laterally from vthe operating v stem 12 is a lug or bit 24 which is engageable selectively against either enlargement 21 in order to slide eithervalve stem 20.

The outer ends of the plugs 18 are formed into valve seats 25 and suitably secured-on' the stems 2O asby means ofmetal disks or washers 25l and nuts 26, are exible washers or valves 27 which are engageable with said seats 25 to close themand urgev them into closing engagement with said seats by the springs 23. v

In order to supply water to the passageways 19, elbow pipes are provided as at 28, being secured in place as by means of hollow nuts 29 'screw threaded at 30 on to the plugs. These hollow nuts 29 havey flanges 31 which engage enlargements 32 on the elbow 28 vand which may have a ground joint with the nuts in order to form a water tight joint. These elbows 28 preferably extend fromA the back wall of a sink and connect one with the hot ywater pipe and one with the coil water pipe in the rear thereof although it is obvious that the manner of connection of the pipes 28 or their place of connection may' be varied within the spirit and scope of the invention. Plates or col lars 33 may be screw threaded on the pipes or elbows 28 for contact against the sink back. In addition, a similar plate or collar as at 34: may be screw threaded at 35 on the casing l0 inorder to `bescrewed against the said sink back.

ln operation, the handle 16 may be turned in either direction. By turning in one direction, it engages "one of the lheads 21 and by turning in the other direction yit en'- gages the other head 21, whereby the valve washers 27 are unseated and water, hot or cold, according to the particular valve opened iowslirom one ofthe elbows 28, past the 'valve27, Iinto passageway 19a,;i`nto casing 10 vand discharging therefrom through the spout 1:1. It will "be realizedthat 'as-the handle 16 turns, it accordingly *turns the stem 12, the latter rotating in the ybea-ring 13 and having zits lug -2engage ya head`2l, pressing the stern 204 slidab'ly inwardly, i compressingfthespring 231 so that whenthe liandl'e is-released,the pressure of ii'ilater against the valve 31 will seat it, assisted by fthe sprinrg23, 'thus urging the valve stem 20 to normal lpo'sitio'n and causing th'e.\'liead 21 rto contact -with the 1 lug 24 and restore ,the stem to?`a"norma"l position. As a result, th'e Valve is self closing.

:It is -tobe understood that'the invention is to vrbe considered as `a valve 'broadly fand notas a -sink'ff'au'cetor basin cock only si'nc'e supply, i' heads integral `with andr adjacent `the inner 'ends Vof said pipes, 1valves -fo'r which the outer ends of sai'dpipe's 'constitute seats,

stems detachably carrying and extending from said valves through'said'pipesand said heads, enlargements at the inner ends of said rods,lexpansive springs on said stems abut- "ting said heads and said enlargements to urge seating of the Valves, and an operating member having a part disposable intermediate said enlargements and selectively engageable with them to impart displacing movement to the valves.

2. A cock or faucet having a casing, alined pipes attachable `thereto for communication with different sources of supply, heads integral with and adjacent the inner ends of and in the vbores of said pipes, valves for which the outer ends of said pipes constitute seats, stems det'achably carrying yand extending from said yvalves, `through said pipes fand said heads, enlargements .at the inner ends of said rods, expansive springs 0n said stems abutting said heads and said enlargements 'to urge seating of the valves, an operating 'm'em'lre'r movable from the casing 'independently of said frods Iand valves, said` operating member vhaving a ipart disposable Aint-'e'rmediate said enlargements and selectively r'eng'age'able with "thein `to V'iinipart displacing i'n'ovenren'tto'the valves, a bearing for the lower "end ofthe operating member and within said casing, -and 'hollow inuts threaded to the pipes y'adjacent their vouter ends vvand constituting 'chambers for 'said valves.

iIn 'testimony whereof I affix myrsignature in presence 1 of two witnesses.
